To all whom it may concern:

Be it known that I, GEORGE A. RAY, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented a new and useful Improvement in Coffee-Urns, of which thefollowing is a specification.

This invention relates to improvements in coffee urns of the type inwhich the receptacle for the liquid coffee is suspended in a boilerwhich is filled or partially filled with water and has suitable meansfor heating the water. In coffee urns of this type, as generallyconstructed, the hot water which is used in making the coffee and whichmust be added to the cofi'eefrom time to time is either drawn directlyfrom the water which surrounds the coffee receptacle in the boiler, orelse a separateboiler, orother source of hot water, is provided tofurnish the water for the coffee. Both constructions are 'undesirable,the first because the water in theproviding a separate boiler andheating the water therein.

One object of the present invention is to overcome these objections byconstructing an urn in which a supply of fresh hot water is provided forthe cofiee, which water is separate from the water in the boiler, and inwhich the heated water of the boiler is utilized for heating theseparate fresh water supply, and a further object is to simplify andimprove the construction of coffee urns in the manner hereinafter morespecifically described and claimed.

In the accompanying drawings, consisting of two sheets: Figure 1 is afront elevation of a coffee urn embodying the invention. Fig. 2 is afragmentary sectional elevation thereof on line 22, Fig. 3. Fig. 3 is asectional plan view thereof. Fig. 4 is a fragmentary sectional elevationthereof on line 4-4, Fig. 3. v

Like reference characters refer to like parts in the several figures.

The coffee urn in its general construction consists of the usual waterboiler A, having a removable cover a, a filler opening a in which watercan be poured if desired, a discharge pipe or? terminating in a faucet aand a water gage at arranged at the outer side of the boiler andcommunicating at its lower end with the pipe a for indicating the amountof water in the boiler. The boiler rests upon a suitable support or baseZ), which in the constructionshown is formed integral therewith and inwhich is arranged a gas or other heater B for heating the water in theboiler. Within the boiler is suspended the coffee receptacle C which inthe construction shown is hung from annularbrackets c 0 which embrace alip on the upper edge of the receptacle and are secured to the innerwall of the boiler A. The coffee receptacle is provided with a dischargepipe 0 leading from its bottom to the outer side of the boiler where itterminates in a faucet 0 and a gage c at the side of the boilercommunicates at its lower end with the pipec for indicating the amountof coffee in the receptacle; Within the coffee receptacle is suspendedthe usual bag or textile filter D of canvasor other suitable material inwhich thecoifee grounds are contained. All of these parts are common incoffee urns of this general type and may be of any suitableand desirableconstruction.

Within the boiler A is arranged a separate water receptacle or containerfrom which water can be supplied to both the boiler and the coffeereceptacle and which is adapted to be heated by the water in the boiler.Any suitable form of water container may be employed for this purpose.That shown consists of a coiled pipe E which is connected at its lowerend with a suitable source of water supply, such as the feed pipe e withwhich it is joined by a connection e 'which extends through the bottomof the boiler. In cities and towns having water systems the feed pipemay be connected directly with the water system. At its upper end,preferably within the boiler A, the pipe E is provided with two arms orbranches F and G, one for supplying water to the boiler and the otherfor supplying water to the coffee receptacle. The branch F has adischarge nozzle or'end 7 which opens into the boiler, and a valve 7"for controlling the discharge from this nozzle, the valve having ahandle, 7 at the outer side of the casing where it is accessible foroperating the valve. The branch G is provided with a valve 9 having anoperating handle g at the outer side of the casing, and beyond the valvehas a pipe 9 arranged above the coffee receptacle C and provided With aspray nozzle 9 for spraying the Water onto the coifee grounds which arecontained in the bag D. The valve handles 7 and g" are readilyaccessible, and when it is desired to fill the boiler or replenish thesupply of Water therein, this can be easily done by openi'ng the valvef. hen Water is required for the coffee receptacle it can ;be

quickly added by opening the valve 9. The Water 1 2 the container orsupply pipe- E is I ur ter the separate Water contai er .01
